Answer:
Cr2O3
Explanation:
In hcp the number of particles per unit cell is 8
Let the metal oxide crystalls = CrO
Number of cathedral voids = 8
The number of atoms of Cr is 8×2/3 = 16/3
Ratio of the number of atoms of Cr and O is M:O = 16/3 : 8 = 16 : 24 = 2 : 3
Cr : O = 2 : 3
Therefore the formula of the compound is M2 O3
